There appears to be a bug in the latest 3.5b4 concerning the horizontal scale.

Whenever I switch back to Track mode from Wave using the buttons, the Wave horizontal scale is reset to 50 Smp/Div regardless of what it was when I went into Track mode. This is true whether Track mode is entered by using the buttons or via inserting a track split.

I have checked on my old 3.4r1 release and the previously selected Wave horizontal scale is retained when switching back from Track. The scale is also retained with the earlier 3.5b I have been using.

So perhaps it might be in the new coding that you mention in your 3.5b4 release post to save the horizontal scale between sessions that has changed something.

Yes, it would be helpful if you could elaborate as I can't seem to reproduce the problem you describe.

I have identified a different problem: if the spectrogram view is enabled, then sometimes the main display sticks in wave mode and will not switch to track mode. I've sort of identified the cause of this but it's proving rather tricky to fix. This may or may not be associated with your reported problem.

Thanks. I've found it now. The problem occurs if you change scale using the up/down arrows next to the H scale control; but not if you use the mouse scroll wheel. I was using the scroll wheel so I wasn't seeing the problem.
